Abstract: ABSTRACT        An air classifier for separating a heterogeneous mixture of particles into heavier and lighter fractions includes an air passageway through which a horizontal primary air stream is flowing, a pair of air deck sections extending along the bottom of the passageway through which deck air is flowing upwardly within and downstream of the passageway, air nozzles located between the air deck sections through which a primary vertical air stream is flowing, the latter also preferably flowing with a horizontal component moving downstream of the passageway, a heavy particle deflector and remover downstream of the second air deck section, and a light particle trapping and removal arrangement downstream of the heavy particle deflector.  The particle mixture is introduced into the passageway over the first air deck section just upstream of the primary vertical air nozzle, whereupon the particles are immediately stratified in horizontal layers of heavy and light fractions by the upward air currents and trans-ported to the end of the passageway by the horizontal air currents, where the fractions are separated from the air flows and removed from the passageway.

Abstract: Abstract An improved seal (10) for use in a universal joint (11) having an elastic seal ring (23) compressed between a pair of right circularly cylindrical sleeves (24,25).  The seal ring is bonded to the sleeves. The sleeves are adapted to have press-fitted relation-ship with association portions of the universal joint, such as the journal trunnion (12) and the bearing retainer (14).  In one form, the elongated extent of the sleeves is parallel to the axis (15) of the journal trunnion (12) and in a modified form, the sleeves (124,125) extend perpendicularly thereto. In each form, a portion of one of the sleeves is disposed adjacent the inner end of the needle bearings (22,122) so as to limit axial movement thereof.  The sleeves are bonded to the seal ring so as to preclude sliding movement therebetween while yet permitting limited axial play in the universal joint thereby to provide long troublefree life of the seal.

Abstract: ABSTRACT OF THE DISCLOSURE          A male die shaft is mounted in a longitudinally movable and rotary manner in a casing, A lever engages on the said shaft. By means of a motor driven cam, the lever is pivoted. By means of a coupling operable by a shift lever and by means of a gear, a tensioning wheel is motor-driven for tensioning the strip. The male die shaft is held in the raised position by a stop member operated by a stop lever. The shift lever and the stop lever are part of a control mechanism pivotably mounted on a shaft and which is operated by a feeler lever. As a result, the coupling and stop member are released and the male die shaft is lowered onto the strip ends. By means of a lever driven by a cam, male die shaft performs a pivoting movement transmitted via a tooth wheel drive to a shaft which imparts an oppositely directed pivotal movement onto a female die located in the base plate. The movement resulting from the pivoting movement of the strip portions produces the frictional heat necessary for welding purposes, By means of the common control mechanism and the non-couplable male die shaft a simple construction of the apparatus is obtained.
